Cal. Health and Safety Code - HSC § 18610.5. Section 18610.5.

(a) Park lot lines shall not be created, moved, shifted, or altered without a permit issued to the park owner or operator by the enforcement agency and the written authorization of the registered owner or owners of the mobilehome or manufactured home, if any, located on the lot or lots on which the lot line will be created, moved, shifted, or altered. (b) No park lot line shall be created, moved, shifted, or altered, if the action will place the mobilehome owner, as defined by Section 18400.4, of a mobilehome or manufactured home located on a lot in violation of any separation or space requirements under this part or under any administrative regulation. (c) The park owner or operator shall submit a written application for the lot line alteration permit to the enforcement agency. The application shall include a list of the names and addresses of the registered owners of mobilehomes or manufactured homes located on the lot or lots that would be altered by the proposed lot line change and the written authorization of the registered owners. The enforcement agency may require, as part of the application for the permit, that a mobilehome park owner or operator submit to the enforcement agency documents needed to demonstrate compliance with this section, including, but not limited to, a detailed plot plan showing the dimensions of each lot altered by the creation, movement, shifting, or alteration of the lot lines. If submission of a plot plan is required, the mobilehome park owner or operator shall provide a copy of the plot plan to the registered owners of mobilehomes or manufactured homes located on each lot that would be altered by the proposed lot line change and provide the enforcement agency, as part of the application, with proof of delivery by first-class postage prepaid of the copy of the plot plan to the affected registered owners. (d) The department may adopt a fee, by regulation, payable by the applicant, for the permit authorized by this section. (e) If the department is the enforcement agency and the application proposes to reduce or increase the total number of lots available for occupation, the applicant shall submit a copy of that application and any information required by subdivision (c) to the local planning agency of the jurisdiction where the park is located.

(c) Nothing in this section shall be construed to create an exemption from the requirements of Division 2 (commencing with Section 66410) of Title 7 of the Government Code.

Cal. Health and Safety Code - HSC § 18612. Section 18612.

Except as provided in Section 18930, the department shall adopt regulations to govern lot access and driveways within parks. The regulations adopted by the department shall establish standards or requirements which protect the health, safety, and general welfare of the residents of parks and shall require proper maintenance of lot access and driveways. The regulations adopted by the department shall provide equivalent or greater protection to the residents of parks than the statutes and regulations in effect on December 31, 1977.

Cal. Health and Safety Code - HSC § 18613. Section 18613.

(a) (1) A permit shall be obtained from the enforcement agency each time a manufactured home or mobilehome is to be located, installed, or reinstalled, on any site for the purpose of human habitation or occupancy as a dwelling. (2) For purposes of this section, the terms “located,” “installed,” and “reinstalled” include alteration, modification, or replacement of the mobilehome stabilizing devices, load-bearing supports, or both. (b) The contractor engaged to install the manufactured home or mobilehome shall obtain the permit, except when the owner of the manufactured home or mobilehome proposes to perform the installation. When a contractor applies for a permit to install a manufactured home or mobilehome, he or she shall display a valid contractor’s license. The contractor shall complete the installation of the manufactured home or mobilehome in accordance with the regulations adopted by the department within the time limitations which shall be established by regulations of the department. The time limitations shall allow contractors a reasonable amount of time within which to complete manufactured home or mobilehome installations. (c) If inspection of the manufactured home or mobilehome installation by the enforcement agency determines that the manufactured home or mobilehome cannot be approved for occupancy due to defective material, systems, workmanship, or equipment of the manufactured home or mobilehome, the contractor shall be allowed a reasonable amount of time, as determined by regulations of the department, to complete the installation after the defects in the manufactured home or mobilehome have been corrected. (d) The enforcement agency shall immediately notify the department whenever any manufactured home or mobilehome cannot be approved for occupancy due to defects of the manufactured home or mobilehome. The report of notification shall indicate health and safety defects and, in the case of new manufactured homes or mobilehomes, substantial defects of materials and workmanship. For purposes of this section, “substantial defects of materials and workmanship” means defects objectively manifested by broken, ripped, cracked, stained, or missing parts or components and shall not include alleged defects concerning color combinations or grade of materials used. If the manufactured home or mobilehome fails the installation inspection because of conditions which do not endanger the health or safety of the occupant, the owner may occupy the manufactured home or mobilehome. If, however, the installation fails inspection due to immediate hazards to the health or safety of the occupant, as determined by the enforcement agency, the manufactured home or mobilehome shall not be occupied. (e) Except as provided in Section 18930, the department shall adopt regulations for the installations and regulations which specify a standard form required to be used statewide by enforcement agencies as a certificate of occupancy or statement of installation acceptance. The department shall transmit a copy of the standard form to all enforcement agencies. An enforcement agency shall not be required to use the standard forms until their existing stock of forms for this purpose is depleted. The regulations adopted by the department pursuant to this section shall establish the requirements which the department determines are reasonably necessary for the protection of life and property and to carry out the purposes of this section. In adopting building regulations or adopting other regulations pursuant to this section, the department shall consider reassembly of the manufactured home or mobilehome, stabilizing devices and load-bearing supports, and utility connections and connectors. (f) The department shall establish a schedule of fees for the permits required by this section commensurate with the cost of the enforcement of this section and the regulations adopted pursuant to this section. Where a city, county, or city and county is responsible for the enforcement, the city, county, or city and county may establish a schedule of fees not to exceed the actual cost of enforcement and not to exceed those fees established by the department where the department is the enforcement agency. Permit fees and reinspection fees shall be paid to the enforcement agency by the permittee. (g) This section does not apply to recreational vehicles or commercial coaches.

Cal. Health and Safety Code - HSC § 18613.2. Section 18613.2.

When the enforcement agency issues an installation permit for a new manufactured home or mobilehome, beginning on July 1, 1980, a copy of such permit shall be delivered to the county or city assessor having jurisdiction where the manufactured home or mobilehome is to be sited.

Cal. Health and Safety Code - HSC § 18613.3. Section 18613.3.

An application for a permit for initial installation of a manufactured home or mobilehome shall be accompanied by a dimensioned plot plan of the lot on which the manufactured home or mobilehome will be installed. The park owner or operator shall sign the plot plan to certify that the dimensions of the lot are correct if the manufactured home or mobilehome is to be located in a park. The applicant shall provide a copy of the plot plan to the manufactured home or mobilehome owner, if the applicant is a contractor, and to the park owner or operator, if the manufactured home or mobilehome is to be located in a park.

Cal. Health and Safety Code - HSC § 18613.4. Section 18613.4.

(a) All manufactured homes or mobilehomes, when initially installed or subsequently reinstalled on a different lot pursuant to Section 18613, shall be installed to resist, in conjunction with vertical loads, either forces from horizontal wind pressures of 15 pounds per square foot or the design wind load of the home, whichever is greater. (b) For the purposes of complying with subdivision (a), all manufactured homes or mobilehomes with manufacturer’s installation instructions that include requirements for tiedowns shall be installed in accordance with all of the following: (1) The manufacturer’s installation instructions. (2) If not included in the manufacturer’s installation instructions, a minimum of four additional tiedowns per section shall be installed to resist the same wind forces in the longitudinal direction of the manufactured home or mobilehome as the total of those forces required to be resisted in the transverse direction. No portion of the tiedown extending beyond the vertical plane of an exterior wall of the manufactured home or mobilehome shall be above the ground. (3) When used, concrete or steel piers shall have mechanical connections to the home and their footing that resist separation of the supports from the home and the footing. Mechanical connections shall not require modifications to the manufactured home or mobilehome. (c) For the purposes of complying with subdivision (a), when no manufacturer’s installation instructions are available that include requirements for tiedowns, the manufactured home or mobilehome shall be installed in accordance with both of the following: (1) Department regulations, which shall include requirements for tiedowns meeting the standards in subdivision (a). (2) The requirements specified in paragraphs (2) and (3) of subdivision (b). (d) For the purposes of complying with subdivision (a), all manufactured homes or mobilehomes may be installed or reinstalled in accordance with plans and specifications signed by a licensed architect or engineer that meet the requirements of this section. (e) Manufactured homes or mobilehomes installed before the effective date of the act that added this section that do not meet the standards in subdivision (a) and need to be reinstalled due to damage caused by wind or seismic forces shall be reinstalled to meet the requirements of subdivision (a) and paragraphs (2) and (3) of subdivision (b), if federal funds are available for grants or direct payment of the additional installation costs. (f) Nothing in this section prohibits the use of alternative materials, installation methods, devices, et cetera, as permitted in Section 18305, as long as the forces specified in subdivision (a) and in paragraph (2) of subdivision (b) are resisted. (g) The department shall adopt emergency regulations in accordance with Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code in order to implement the purposes of this section. (h) The department shall develop standards for mechanical connections for concrete block supports that connect the blocks to the manufactured homes or mobilehomes and their footing and resist the separation of the supports from the home and the footing. By the adoption of the act that adds this subdivision, it is not the intent of the Legislature that the concrete blocks used as vertical supports be required to be mechanically attached to the manufactured homes or mobilehomes and their footings. (i) This section shall not apply to the installation of any manufactured home or mobilehome for which escrow has been opened in accordance with Section 18035 prior to the operative date of the act that adds this section. (j) This section shall become operative 60 days after the date that the act that adds this section is chaptered.

Cal. Health and Safety Code - HSC § 18613.5. Section 18613.5.

The Department of Housing and Community Development, with the review and advice of the Seismic Safety Commission, shall adopt such rules and regulations as are necessary to ensure that purchasers of all manufactured homes and mobilehomes installed for human occupancy pursuant to Section 18613 are offered earthquake resistant bracing systems which meet generally accepted seismic safety standards for the reduction of damage and for the protection of the health and safety of the occupants. Such rules and regulations also shall include provisions for establishing a process and a fee schedule for the design review and certification by the department. To the extent practical, the department shall be responsible for notifying owners of existing licensed manufactured homes and mobilehomes that a certification process has been established so that when considering purchase of a bracing system the owners can determine if the product or system is certified by the department. The fees established by the department shall be sufficient to pay for the development of the design criteria and standards and the costs for the design review and certification of the products or systems.

Cal. Health and Safety Code - HSC § 18613.7. Section 18613.7.

(a) A permit shall be obtained by the installer from the enforcement agency each time an earthquake resistant bracing system is installed, replaced, or altered on any manufactured home or mobilehome. The enforcement agency shall inspect the installation of these bracing systems to ensure compliance with the regulations adopted by the department. (b) The department shall adopt regulations governing the installation of earthquake resistant bracing systems. The enforcement agency shall adopt a fee schedule which shall not exceed the costs of the issuance of the permit and inspection required by this section.

Cal. Health and Safety Code - HSC § 18614. Section 18614.

If the installation of a manufactured home or mobilehome by a contractor has failed the inspection of the enforcement agency and the contractor has failed to perform corrections to remedy the reasons for the failure within the time permitted by regulations of the department adopted pursuant to Section 18613, the enforcement agency shall promptly notify the registrar of contractors of such fact and the name of the contractor. Upon such notification, the registrar shall investigate the actions of the contractor. Failure by the contractor to comply with the provisions of Section 18613 and the building standards referenced therein and the regulations adopted pursuant thereto may constitute cause for disciplinary action.
